Noble gases don't like forming molecules because they have complete outer
electron shells. And are thus already in their lowest energy state.
However the environment around a supernova where atoms get ionised is
exactly the kind of place I would expect to find Noble gases forming molecules.
Because once it's ionised it will form ionic bonds with other elements trying to
find a lower energy state, just like any other chemical would.
